I have an internal hard drive which I put in an hard drive enclosure and have been using as a backup hard drive for the past few months...I just bought a bigger hard drive for my Macbook so I backed all my info up to my external hard drive and now that the new hard drive has been successfully installed, I can't seem to boot my external hard drive. When I plug it in I get the message "USB Over Current Notice. A USB device is currently drawing too much power. The hub to which it is attached to will be deactivated."
I've tried repairing disk permissions, I've switched out the USB cable, and I've tried it on my mom's (brand new) iMac. This thing is no longer working, and I'm not sure why since my upgrading my macbook's hard drive shouldn't have affected my external hard drive whatsoever. My Macbook is plugged into the power adapter, and my iMac is obviously plugged in to a power source as well.
Again, I've used this hard drive to back up both the iMac and the Macbook successfully in the very recent past, and all of a sudden it's not working - I'm not even using the full amount of space in the external hard drive. What is the problem here and how do I fix it? All my old files are on that hard drive and now I can not longer access them.
